为了提高钢锭冒口的电磁感应加热装置的效率并且降低其能耗,提出了一种磁轭的优化方法。通过ANSYS多物理场耦合仿真计算,主要分析了磁轭对于钢锭冒口的磁场分布、加热效率以及钢锭凝固的影响。结果表明,当磁轭扩展至线圈面积的130%且厚度增加到120 mm的时候,在相同工况的条件下会抑制边缘的磁漏,使钢液表面的磁感应强度增加了约80%;焦耳热功率提高了约2.5倍;同时,在冒口区域的温度分布更加均匀,钢锭凝固延缓,冒口线补缩通道的时间延长了18 min。该优化设计在相同激励电流692 A的条件下,将加热功率从优化前的10.67 kW提升到了26.58 kW实现了“小电流、大功率”的高效加热模式并且降低了线圈损耗。
To improve the efficiency and reduce the energy consumption of an electromagnetic induction heater for steel ingot riser, an optimization method for the yoke is proposed. Using ANSYS multi-physics coupling simulation, the effects of the yoke on the magnetic field distribution, heating efficiency, and solidification of the steel ingot riser were analyzed. The results show that when the yoke is expanded to 130% of the coil area and its thickness is increased to 120 mm, magnetic flux leakage at the edges is suppressed under the same working conditions. This increases the magnetic flux density on the molten steel surface by approximately 80% and increases the Joule heating power by about 2.5 times. Meanwhile, the temperature distribution in the riser region becomes more uniform, solidification of the ingot is delayed, and the feeding channel duration at the riser line is extended by 18 min. Under the same excitation current of 692 A, this optimized design increases the heating power from 10.67 kW before optimization to 26.58 kW, achieving an efficient heating mode of "low current, high power" while reducing coil losses.
